+## TreeSelect 分类选择
+
+### 使用指南
+在 index.json 中引入组件
+```json
+{
+  "usingComponents": {
+    "zan-tree-select": "path/to/zanui-weapp/dist/tree-select/index"
+  }
+}
+```
+
+### 代码演示
+可以在任意位置上使用 zan-tree-select 标签。传入对应的数据即可。
+```html
+<zan-tree-select
+  items="{{ items }}"
+  main-active-index="{{ mainActiveIndex }}"
+  active-id="{{ activeId }}"
+  bind:navclick="handleNavClick"
+  bind:itemclick="handleItemClick"
+/>
+```
+```javascript
+Page({
+  data: {
+    // ...
+  },
+
+  handleNavClick({ detail = {} }) {
+    this.setData({
+      mainActiveIndex: detail.index || 0
+    });
+  },
+
+  handleItemClick({ detail = {} }) {
+    this.setData({
+      activeId: detail.id
+    });
+  }
+});
+```
+
+### API
+
+| 参数       | 说明      | 类型       | 默认值       | 必须      |
+|-----------|-----------|-----------|-------------|-------------|
+| items | 分类显示所需的数据，具体数据结构可看 数据结构	 | Array | [] | |
+| main-active-index | 左侧导航高亮的索引	 | Number | 0 | |
+| active-id	 | 右侧选择项，高亮的数据id	 | String | Number	 | 0 | |
+
+### Event
+
+| 事件名称       | 说明      | 回调参数       |
+|-----------|-----------|-----------|
+| navclick | 左侧导航点击时，触发的事件	 | index：被点击的导航的索引 |
+| itemclick | 右侧选择项被点击时，会触发的事件 | data: 该点击项的数据 |
+
+### 数据格式
+#### items 分类显示所需数据的数据结构
+`items` 整体为一个数组，数组内包含一系列描述分类的 object。
+
+每个分类里，text表示当前分类的名称。children 表示分类里的可选项，为数组结构，id被用来唯一标识每个选项
+
+```javascript
+[
+  {
+    // 导航名称
+    text: '所有城市',
+    // 该导航下所有的可选项
+    children: [
+      {
+        // 可选项的名称
+        text: '温州',
+        // 可选项的id，高亮的时候是根据id是否和选中的id是否相同进行判断的
+        id: 1002
+      },
+      {
+        // 可选项的名称
+        text: '杭州',
+        // 可选项的id，高亮的时候是根据id是否和选中的id是否相同进行判断的
+        id: 1001
+      }
+    ]
+  }
+]
+```
